Walnut Hills was playing the Sycamore High School football team at the stadium at the time of the collapse.

The collapse happened just before halftime in the Sycamore student section.

"We were just standing there and then out of nowhere it was crazy. We just all fell it was like a dang roller coaster or something," student James Keefe said.

Hamilton County dispatchers said several people were injured in the collapse. They were taken to Bethesda North Hospital to be checked out.

About a dozen people fell 3 or 4 feet from the bleachers onto the track.

"I was just standing there and all of the sudden you felt like a shudder and then we just started going towards the ground. I didn't even realize what was happening until I was on the ground and I was bleeding," student Nathan Gregg said.

Three people were hospitalized and less than a dozen people were treated at the scene for cuts, bruises and other minor injuries.

Police said it appeared that the railing broke off at the base while students were leaning and standing on it to cheer.
